Abstract: The present invention is a method and a vehicle-mounted apparatus for laying pipelines in which adjacent pipe sections are joined by the technique of magnetically impelled arc butt welding (MIAB). A MIAB welding head having a welding axis is mounted on a transportable platform. A pipe guide capable of engaging a welded pipe string is located rearwardly of the welding head. The pipe guide maintains alignment of the string with the welding axis. The apparatus includes pipe feed means maintaining alignment of a next pipe to be laid with the welding axis and the pipe string. The platform is rotatably mounted on the vehicle and tilts around a horizontal axis. The vehicle is provided with pivoting steerable tracks.

Abstract: Use of (+)-(11R,2′S)-&agr;-2-piperidinyl-2,8-bis(trifluoromethyl)-4-quinolinemethanol or a pharmaceutically acceptable salt thereof substantially free of its (−)-enantiomer in the manufacture of a medicament having reduced side-effect compared to the racemic (±)-(R*,S*)-&agr;-2-piperidinyl-2,8-bis(trifluoromethyl)-4-quinolinemethanol for treating or preventing malaria in a subject. A method of treating or preventing malaria with reduced side-effects comprising administration of (+)-(11R,2′S)-&agr;-2-piperidinyl-2,8-bis(trifluoromethyl)-4-quinolinemethanol or a pharmaceutically acceptable salt thereof substantially free of its (−)-enantiomer.

Abstract: The present invention relates to the use of (±)-R*,S*)-alpha-2-piperidnyl-2,8-bis(trifluoromethyl)-4-quinolinemthanol and in particular (−)-(11S,2′R)-alpha-2-piperidnyl-2,8-bis(trifluoromethyl)-4-quinolinemthanol in the treatment of disorders in which the reduction of purinergic neurotransmission could be beneficial. The invention relates in particular to adenosine receptors, and particularly adenosine A2a receptors and to the treatment of movement disorders such as Parkinson's disease.

Abstract: Selective 5-HT.sub.1A antagonists radiolabelled with .sup.3 H or .sup.11 C are radiolabelled ligands useful, for example, in pharmacological screening procedures and in positron emission tomography (PET) studies.
